An investigation has been launched after a man was found lying in a Merseyside street with serious head injuries in the early hours of the morning.

Officers were called to Christmas Street, just off Stanley Road in Kirkdale, at around 6am today after a passerby found a 59-year-old man collapsed in the road.

Paramedics arrived at the scene and took the man, who had sustained serious head injuries, to hospital.

He is currently being treated for his injuries and remains in a serious condition.

An investigation has been launched into how he sustained the injuries, with one line of enquiry whether he was assaulted.

The scene has been cordoned off and house-to-house enquiries are on-going in the area, while CCTV footage is also being sought from the nearby area.

Detectives from Merseyside police are currently trying to retrace the man’s steps between 4am and 6am in a bid to find out what may have happened to him, and are appealing for anyone with information about where he may have been or how he may have sustained the injuries to get in contact with them.
